DIE FOR usE IN MAKING BARBED FENCING.

SPECIFICATION forming part of Letters Patent No. 450,045, dated April *7, 1891.

- Application filed July 30, 1888.

To all whom, it may concern:

Be it known that I, JosEPH H. TEMPLIN, a citizen of the United States, and a resident of Reading, in the county of Berks and State of Pennsylvania, have invented certain new and useful Improvements in a Combination of Dies forUse in Machinery for Making Barbed Strips, of which the following is a specification.

This invention consists of improved contrivances of dies for producting two barbed strips from a double blank strip by making slits at intervals along the strip in two parallel lines and a diagonal line connecting the parallel lines and making other slits in line with and opposite to the parallel lines of the first slits across the diagonal lines by which the blank strip is separated in two parts and pointed barbs are out on the edge of each part thus separated.

The invention comprises the combination of bending-dies with the improved slittingdies for bending the barbs so cutfor the required lateral projection from the strip, as follows, referring to the drawings, in which Figure 1 represents face views of slittingdies of my improved contrivances together with other slitting-dies and bending-dies used therewith. Fig. 2 represents adiagram of the blank strip, showing the effect of the dies on it. Fig. 3 is a side elevation of the slitting and'bending dies with a blank strip between them. Fig.4 represents face views of theimproved slitting-dies in a modified arrangement together with other slitting-dies and the bending-dies. Fig. 5 is a diagram of the strip, showing the effect of the dies of Fig. 4.

I .provide two pairs of slitting-dies a I), both having cutting-edges partly in two parallel lines o and partly in the intermediate diagonal line cl, connecting the parallel lines, said lines being apart from each other the width of the barbs to be made, the diagonal lines of both pairs of dies being inclined in the same direction, and the length of one pair of the dies being equal to the length of two barbs and two base-webs, by which the barbs remain joined to the strips, the other pair being the length of two barbs only and the 4 two pairs being located close together. The longer dies Serial No. 281.398. (No model.)

are here represented as first in the order of arrangement, but they may be second. The effect will be substantially the same. These dies make two slits a b of like form in the blank strip 0'', but differing in length, one in advance of the-other and their contiguous ends, respectively, in the different parallel lines of the cutting-edges and terminating in one and the same transverse line of the strip. The blank strip 0 is fed along the length of these two pairs of dies at each operation, so that the relations of the contiguous ends of the preceding slit a and the successive slit -b are the same as those of the slits a and b, thatare made together-that is to say, the slits are all uniformly the same as to their longitudinal order. Next following these slitting-dies are two pairs of parallel-edged slitting-dies c f, located apart from them the length of the retaining-webs g to be left on barb-strip 72, and apart from each other the length of the similar retaining-web g to be left on barb-stri p h. They cut the slits 2' each way from the diagonals of slits a and b and complete the cutting of the barbs j and the cutting of the barbed strips apart, the slits of one pair terminating in the uncut webs g 9, left at the ends of the short slit 1), and the slits of the other pair cutting through to the ends of the long slit a alternately in the dif-- ferent parallel lines of slits a, so that the barbs are disposed in pairs on each barb-stri p alternately. Next after the slitting-dies e f are bending-dies k] of suitable punch and erally to the strip and arranged in two pairs which bend the barbs alternatelyin opposite directions.

Both pairs of the slitting-dies a b may be made the length of the short pair in Fig. l and be located apart from each other the length of a connecting-web for the barbs, as represented in Fig. 4, provided web-cutters n 0 be employed for subsequently cutting apart the webs left at p g by such dies; but this is a substantially equivalent device which I consider included in my invention.

WVhat I claim, and desire to secure by Letters Patent, is
